SURGICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 735,400, dated August 4, 1903. Application filed April 22, 1903- Serial No. 153,737. (No model.)

To all whom it may concern:

Be it known that I, RICHARD P. MGOULLY, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful well understood by those who are familiar with the art. It is absolutely essential that an instrument which is to be used for surgical purposes more than once shall be adapted to cleansing in hot water and inchemicals which will render the instrument perfectly antiseptic. It is therefore important that the parts should be able to withstand a high temperature and withstand the action of chemicals. It is also important that all the parts of, the instrument be accessible for the purpose of cleansing them with force when necessary.

With these objects in View my invention consists in employing a main tubular portion of the instrument which surrounds the shanks of two members which are capable of relative longitudinal movement and. in incasing the outer ends of these two members in a suitable I manner. The ends of the members are so held that they may be moved longitudinally relatively to each other for the purpose of causing a curvature of the ends. The construction will be more clearly seen on an inspection of the accompanying drawings, in which- .Figure 1 is a side elevation of an instrutnent embodying my invention with the adjustment so effected that the end is curved. Fig. 2 shows a longitudinal cross-section of the main body or tube portion of the instrument,together with the adjusting mechanism. Fig.3 is a side elevation of the main operatingmember or rod. Fig. 4. is a side elevation of its shorter companion member or controllerrod. Fig. 5 is a side elevation, partly in section, of the covering for the flexible ends of the instrument. Fig.6 is a longitudinal crosssection of the tip employed to hold the flexible ends in position.

1 is a tubular member, which constitutes the main body portion and handle of the instrument.

2 is the operating-rod, which is provided with a screw-threaded portion at the lefthand end, as shown in Fig. 3, and which is semicylindrical at its central portion. A portion at the right is thinned down, so as to be very flexible and spring-like. 22 is a screwthreaded portion at the extreme end, which is semicylindrical. In Fig. 4 is shown the companion member or controller-rod 3, which is preferably semicylindrical to correspond with the semicylindrical portion of the operating-rod 2.

is a pin carried by the controller member, whichis adapted to coact with the perforation 10in the tube when the parts are assembled. p

31 isa flattened flexible or spring-like portionof the controller-rod.

32 is the semicylindrical end which is provided with screw-threads corresponding to the screw-threads 22. The combined ends 22 and 32 of the operating and controller rods form a complete screw-thread.

Fig. 5 shows the flexible covering, preferably a coiled spring, which fits into the end 11 of the. tube 1 and covers the flexible portions of the controller and operating memhere; The end 42 of the covering fits into a recess 51 in the tip 5 when the tip 5 is screwed onto the ends of the controller and operating members, it being provided withscrewthreads for coacting with the screw-threads 22 and 32. T

The parts thus far described are assembled by first inserting the controller member 3 in the tube 1, so that the pin 30 projects into the hole or recess 10 in the tube. This prevents threaded interior 60, adapted to coact. with the adjusting-nut 6.

ing-nut from having a longitudinal movethe screw-threads on the operating-rod. This nut 6 is provided with a recessed portion 61 of a slightly greater length than the shouldered extension 12 of the tube 1.

It will be seen on inspection of the drawings that a change in the relative longitudinal positions of the operating and controller rods 2 and 3 will cause the flexible ends 21 and 31 to be curved to the one side or the other, depending on whether the operatingrod is forced outward or drawn back. This adjustment of the longitudinal position of the operating-rod 2 is effected by means of To prevent the adjustment relatively to the tube 1 and to force the operating-rod 2 to move longitudinally, no

matter in which direction the nut 6 is re-- volved, I have provided the guide member 7, which in this preferred form consists of an annular member free to move upon the tube 1 and provided with a screw-threaded portion 70 for coacting with the screw-threads 62 of the adjusting-nut 6. When the parts are in the position shown in Fig. 1, it will be seen that the combined adjusting-nut 6 and guide member 7 cannot have a longitudinal movement relatively to the tube 1, but that the rotation of the nut 6 will cause the operatingrod 2 to move in or out, and thus to curve the opposite end of the instrument.

13 is a plate attached to the tube 1, forming a convenient gripping means for the hand.

The construction of the instrument will therefore be seen to be simple and of economical manufacture. All the parts are preferably of metal. The operation is effective and thoroughly reliable, and the instrument is so dismemberable that it may be readily cleansed in all of its parts, so as to make the instrument perfectly antiseptic.

What I claim is- 1. An instrument of the character described including a tubular member, a controller-rod mounted therein, an operating-rod coacting with the controller-rod and with the tubular member, said rods having flexible portions, aremovable covering for the flexible portions, a tip for removably connecting the extreme ends of the rods and means for moving the operating-rod relatively to the controller-rod, for the purpose specified.

2. An instrument of the character described, including an operating-rod and a controller-rod movable longitudinally relative to one another and having flexible and "spring-like portions, a spring-like covering for the flexible portions and a removable tip securing the ends of said rods together and holding in place one end of the covering, and means for causing a relative longitudinal movement between said rods in order to cause a curvature of the flexible portions of the rods. v

3. An instrument of the character described including a tubular body member having a shouldered end portion, operating and controller rods mounted in said tube, one end of the operating-rod having a screwthreaded portion, a nut mounted to coact with the screw-threaded portion and having a recess to hold the shouldered portion of the tubular member, and a guide member coacting with the adjusting-nut and the shouldered portion to prevent the nut from having longitudinal movement relatively to the tubular member, and a removable covering for the flexible ends of said rods.

4. An instrument of the character described including a tubular member having a recess therein, a controller-rod having a flexible portion, a projection carried by the controller-rod and engaging the recess in the tubular member, an operating-rod having a flexible portion and mounted in said tubular member and adapted to coact with the con troller-rod, said rods being removable from said tubular member and means for securing the ends of the rods together.

5. An instrument of the character described including a pair of rods having flexible portions, means for moving said rods to cause a curvature of the flexible portions, a removable covering for said rods and a tip for securing said rods together at one end.

6. An instrument of the character described, including an operating-rod and a controller-rod movable longitudinally relative to one another and having flexible and spring-like portions, a covering for, the flexible portions and a removable tip securing the ends of said rods together, and means for causing a relative longitudinal movement between said rods in order to cause a curvature of the flexible portions of the rods.

7. An instrument of the character described including a pair of rods, a tubular member, an adjusting-nut for one of said rods, a guide member freely mounted on said,

tubular member and coacting with the adjusting-nut to prevent its longitudinal movement and a curvable portion operated by the adjusting-nut and said rods.

8. A uterine replacer including a relatively stationary tubular member, an operating-rod having a flexible end portion, a controller-rod having a corresponding flexible end portion, both of said rods being surrounded through part of their lengths by said tubular member and removably secured therein,.a removable troller-rod may be removed and disassembled tip for securing the flexible ends of the rods tofor the purpose of cleansing. gether' and means coaeting with the tubular member and the operating-rod whereby the RICHARD MCOULLY' 5 rods may be made to curve to one side or the Witnesses:
